  1. 4. - group of students according to their academic ability. This is also known as ability grouping where students place together in respect to their achievements or similar instructional level
  2. 5. -consisting of different, distinguishable parts or elements. The word is used in a more specific way in the context of chemistry to describe a mixture consisting of two or more different substances or the same substance in different phases of matter
  3. 6. - able to dissolve other substances
  4. 9. - starting materials in a chemical reaction. Reactants undergo a chemical change in which chemical bonds are broken and new ones formed to make products
  5. 10. - the ability to be dissolved, especially in water.
  6. 11. - substance made by mixing other substances together.
  7. 12. - Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and the lower the pH of the solution.
  8. 13. - reducing the concentration of a given solute in its solution. The chemist can do it simply by mixing with more solvent
  9. 14. - a metal made by combining two or more metallic elements, especially to give greater strength or resistance to corrosion.

  1. 1. substance that is formed as the result of a chemical reaction. In a reaction, starting materials called reactants interact with each other. After passing through a high energy transition state (achieving the activation energy for a reaction),
  2. 2. - A base is a substance that reacts with an acid in an acid-base reaction.
  3. 3. - chemical solutions that have high concentrations of a large amount of solute in the solution. If a solution is concentrated to the point where no more solute will dissolve in the solvent, it is said to be saturated.
  4. 7. Mass - average mass of atoms of an element, calculated using the relative abundance of isotopes in a naturally occurring element. Atomic mass indicates the size of an atom.
  5. 8. - smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds.
  6. 10. - the minor component in a solution, dissolved in the solvent.
